Inphi Device Drives 10-Gb/s LRM Systems

Inphi(R) Corp. has developed their model 3200EC 10-Gb/s dual clock data recovery (CDR) device for use in 10GBase-LRM small-form-factor-pluggable (XFP) modules. The single-chip device employs the firm's patented electronic dispersion compensation (EDC) technology with XFI-compliant transmit and receive CDRs in a compact 7 x 7 mm QFN package. The single device can replace as many as three separate chips in an XFP transceiver module. With the firm's model 1348TA linear transimpedance amplifier (TIA), the 3200EC provides a complete solution for cost-effective XFP modules.

According to John Monson, Vice-President of PhyOptik Marketing at Inphi, "Currently, there are no XFP solutions for 10 Gigabit Ethernet backhaul on the installed base of legacy multimode fiber. The 10GBASE-LRM standard was specified to solve this problem, but has previously not been available in this form factor due to its unique combination of power, performance and small size. The 3200EC has been specially designed to enable this new generation of Ethernet connectivity for enterprise switch customers." The 3200EC is available in a RoHS-compliant 7 x 7 mm 48-pin QFN package.
